HI all, major noob here...I need a little help. I found a machine with a p5k deluxe motherboard, I replaced hard drive with new one and im trying to install linux on to drive. I think I must turn off secure boot in order to do this or delete the pk key, but i cant find any advanced boot options within bios to do so. I changed the boot order anyway just for kicks and when it does boot into it..it displays for 5 secs...then quits displaying.. Please help.
